Thank you for the explanation, rogge1722. I understand now why TT does not use the worksheet for line18 in my case.
Unfortunately, I have been using the online version for years now, not the downloaded version. Is there perhaps anywhere I can make an entry online to "trick" TT into thinking I made an adjustment to line 1a without actually changing the value of line 1a?
I know this is a long shot but might as well try, it's worth more than $600 in taxes to me.
Thank you again!
