Same problem here at first. TT should take care of this automatically as info gets transferred from Fed 1040. I don't know all the other possibilities but here's what seems best: If you contributed $6000 of "after tax money" to trad IRA, didn't or couldn't take deductions due to income limits, and that entire balance was converted to Roth IRA, then make sure your basis on the PA-40 is $6000. The default value TT inputs is $0, which wrongly inflates your PA tax due. Basis is just the term for money invested that's already been subject to income taxes and nobody wants to be taxed twice.
