I do not have your answer; however, I am having the same problem!  Finding your message let's me know the problem is not with what I am putting in or not putting in, but with the program.  It is also telling me I owe for last year, and also have penalties to pay … all related I'm sure.  Let's hope the company see this fast!!!

This is still not corrected.  I'm having same problems.  I think I owe $1.08 underpayment penalty, but form 2210 is not required, I can't delete it, and I don't know how to add $1.08 to 1040 line 23.

Any news yet on this being fixed?

I am mailing my return in minus the 2210 and if I owe a very small penalty I’m sure the IRS will take it.
Two phone calls to Turbo have been worthless.  I will no longer use them.
