Deductions & credits

I've tried to do the solutions presented in several of the replies in this chain - NONE of them worked - I tired many variations of my own, and still could not get the error message to go away which PREVENTS e-filing of the federal return.  I went through the entries several times and could not find where the error message would have come from.  

The only ways I could make it work was 1) delete all contributions and loose some of my federal refund OR 2) just print (with whatever error exists) and mail the return - which is the solution I used.

Not happy with this aspect of Turbotax since even Turbotax has no solution that worked for me and I wasted much time trying to fix this issue with no result.
