Supposedly/as a basic rule, the regular Rifle Corps would have had a Artillery Regiment and the Guards Rifle Corps a Artillery Brigade + lots more usually.
Guards so far has not been looked at. TOEs:
Note: See this Post further down for these two initial TOEs.
Those TOEs seem to use a type of "1xDivision+4xRifle Brigades" as an TOE, I can't say for sure in how far this makes sense, Soviets developed the Corps structure new during that time and appear to first have used Brigades and then later in 42 Divisions.

The first Corps TOE 06/42 has a "arrival date" between two Rifle Division TOEs (03/42 - 08/42), It's TOE is a multiple of 1xDiv+4xBrigade+2xArtRegiment, so it is not following the 3xRule.
The Artillery are 2xOB:2433 with 1192Men each. Therefore it is missing +50Support Squads. - 42b
The Second Corps TOE 08/42 has the same Date as the Rifle Division's TOE 08/42, but it is also not following the 3xRule. It again uses a multiple of 1xDiv+4xBrigade+2xArtRegiment, and so it is not following the 3xRule.
The Artillery are 2xOB:2433 with 1192Men each. Therefore it is missing +50Support Squads.
The Corps TOEs after that have the "correct" 3xRule applied as can be seen. But they have additional Artillery (Regiments/Brigades) which is by itself seen by the additional Guns, but it was forgotten to add the Support-Manpower for those Regiments.

The TOE 12/42 is first to have proper 3xRule applied.
It has the Artillery Regiment OB:2433 which has 1192Men (do not know if this TOE is using correct manpower, but seems alright). So the TOE seems to be missing +50 Support Squads. - 43
Dated 06/43 and it is using Artillery TOE OB:UNKNOWN, looks like OB:2434 but is using the wrong guns for that, so not sure what's the background/intend here.
See this Post further down for more info. - 44
The 06/44 Corps TOE is using another AT-Gun than the 06/44 Rifle Division TOE which seems like a minor error.
It gains an additional Element through the Artillery Regiment. The Battalion used there should be the Artillery OB:2435 with 504Men (do not know if this TOE is using correct manpower, but seems alright).
Actual Manpower of the Battalion was 512Men (game has 504Men which is fine).
So 512Men-(8gunx8Men+8gunx9Men)=376Men
376/20=18,8=+19Support Squads→+HQ staff (+20Support seems fine until we know more) - 45
The 12/44 TOEs has the same Artillery Battalion as 06/44.
It gains an additional Element through the Artillery Regiment. The Battalion used there should be the Artillery OB:2435 with 504Men (do not know if this TOE is using correct manpower, but seems alright).
Actual Manpower of the Battalion was 512Men (game has 504Men which is fine).
So 512Men-(8gunx8Men+8gunx9Men)=376Men
376/20=18,8=+19Support Squads→+HQ staff (+20Support seems fine until we know more)
