Be sure that you first entered the non-deductible contribution in the IRA contributions section and you specified that it was non-deductible. The go through the 1099-R interview so that the after-tax "basis" will be applied in the part of the interview after the 1099-R entries screen.
Enter IRA contributions here:
Federal Taxes,
Deductions & Credits,
I’ll choose what I work on (if that screen comes up),
Retirement & Investments,
Traditional & Roth IRA contribution.
OR Use the "Tools" menu (if online version under My Account) and then "Search Topics" for "ira contributions" which will take you to the same place.
