Deductions & credits

Yes, actually.  The spot you circled.  I assume that's from the worksheet.  When you enter the cash amounts in the Step by Step, they total in that spot, as expected.  BUT - it doesn't carry from there to the second spot you have $600.  And as best as I can tell (many, many years using TT and also being a former beta tester, and many years developing financial software in banks), that's a bug that needs to be squashed.  Because if not, lots of people who don't itemize but do enter it their cash charity and don't think to check to see if it carried will pay too much Federal income tax.

 

Now, if by chance, you see it carry while I don't, then something is inconsistent.

 

Looks like the right people are looking at this!
