If you returned income to your employer, then your employer should issue a corrected tax form to reflect the actual amount paid to you in the tax year.  If this is retirement income, then your employer should provide a Corrected 1099-R. 

Contact your retirement plan administrator about this document.  Once you receive the Corrected 1099-R, you will complete an amended tax return and report the amount shown on the Corrected 1099-R.

See the TurboTax FAQ below for steps on how to amend your return.  Select the tax year that applies.
