How do I specify the following year for a 1099-R?

What code is on your 1099-R?

I have a 2018 1099-R that shows P for the code since the refund is supposed to be taxable in 2017.  I have not yet filed my 2017 return so I'd like to include it now rather than amending the it later.  The code selection options in TurboTax shows P but that sets it to 2016 (since it thinks the 1099-R is for 2017).

You want to enter the amount of your excess contributions under Miscellaneous Income, not in the 1099-R retirement section.  Follow these instructions to claim this income in 2017.  You will disregard the 1099-R next year since you will be claiming the income correctly this year.
