How much do i report on the gross distribution if i'm planning to spread it over 3 years? i took out $11,700, do i put that amount or do i divide it by 3 and put 3,900

You enter the Form 1099-R Exactly as received.  Once you finish the 1099-R entry you will be asked a series of questions concerning the withdrawal.  A couple of those questions will concern Covid-19 and how you want to report the withdrawal. 

You enter the 1099-R and select that it was COVID related distributions and answer the questions.    The 3 year repayment is done the the 8915-E form by TurboTax.

TurboTax still has problems handling this correctly.
