I always try to  finish the "Accounting Work" before trying to figure out how to get things on to the tax return.

A lot of times I end up with an old fashioned columnar pad, to work out problems, and have a final trial balance before I even start entry for a return.

I this case look at the balance sheet. You can't have a final return if you have any assets or liabilities left, so you need to figure out what the correct journal entries are to get rid of anything remaining. (You have to have a reason for the accounting entries you make - don't just plug stuff to make it go away.) Might need to dig out an old accounting theory text book.

Thanks for the response Jeff.  Yes I know my entries.  My problem is that pro series carries forward the negative retained earnings from 2020 and I have to get rid of it in pro series as zero is the ending balance. 

The smart worksheet that ties to the retained earnings line is scd m-2  but I don't know how to code or describe the closing of the company and of course this can affect the k-1 reporting.

Do I just write in closing corporation as an add back?

That will work.

If anyone else has this problem I found a box to x  on scde m-1 that allowed me to zero out the retained earnings with no impact to k-1 which is what I wanted.
