Got it. Thanks

Last question if you don't mind. In regards to my first question. I'm amending the 2021 tax return. The client deducted the 45K (which he had basis for) on the original return. The bookkeeper just discovered 75K that should not have been treated as income and changed the net to a negative 120K. I plan on amending the 1120S but if he can't deduct anything over 45K, because of the basis limitation, should we amend the 2021 1040?
