RMD

Go back through the entries that you've made for your 1099-Rs.  You'll have to adjust the RMD at the place where you entered it.

@Brook23 

On each 1099R you need to say Yes it was the RMD and only enter the amount from box 1 on that single 1099R for the RMD, not the total RMD for all and even if it is more or less than the total.

If all else fails, try deleting the Form 5329 from your tax return and allow it to regenerate.
