Hi,

My client filed 1120 C in March 2025, it turned out it is the S Corp.

Now we need amend C Corp return to zero, then file as S Corp.

Having issue to amend 1120C, the number does not flow to 1120X like 1040X. So had to manually enter the income/exp originally filed.

Federal seemed ok.

We have issues with MASS state, no place to manually enter the balance sheet number, and the state tax at asset.

Anyone can help?

Thanks!
