On the 1099R the taxable amount is larger than the gross distribution.

[Anita01]

If this is an error message you are receiving, you would need to go back to Federal Taxes, Wage and income, retirement income  to edit the 1099-R in question.  This is usually a decimal point or comma error in your entry.  If you are saying you actually have a 1099-R form that shows a larger taxable amount than gross, that would be error made by the issuer and yo should call them for a corrected form.
