I am trying to enter a 1099-R for a refund of excess deferral to a 401k plan for the current tax year. The TurboTax online help says to enter the 1099-R with a P code but specify the following year (2018). How do I specify the year when entering a 1099-R?
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.
