Have a 401 k that was rolled over into a regular Ira why is my return showing it as a filly taxable event ?

A direct rollover from a 401(k) to a Traditional IRA is not taxable.

Please enter your form 1099-R in TurboTax, paying attention to the code in box 7 which must be G. Then follow the TurboTax interview and indicate that it is a rollover. TurboTax will exclude the rollover from taxation.

First, confirm that TurboTax is treating it as taxable by seeing that it is being included on Form 1040 line 4d.  If it's appearing there:

What is the code in box 7 of the Form 1099-R provided by the payer?

Does the Form 1099-R show a nonzero taxable amount in box 2a?

Does the word ROLLOVER appear next to line 4d of Form 1040?
