It depends - Form 4598 is the form used to dispute a 1099-R. You would not enter this form in TurboTax.
Instead if you received a 1099-R and it was a rollover distributions (which would apply to you taking out the money for 60 days then putting the money back into the same account). You will need to report this 1099-R distribution on your tax return but none of it will be taxable. Just make sure that when you are reporting this information into TurboTax that for the question "What Did You Do With The Money From (your retirement fund)?", answer "I moved the money to another retirement account (or returned it to the same retirement account)" (see screenshot)
To enter 1099-R information in TurboTax, log into your tax return (for TurboTax Online sign-in, click Here and click on "Take me to my return") type "1099r" in the search bar then select "jump to 1099r". TurboTax will guide you in entering this information.
Please note that if the code in box 7 is "G", then this is automatically a rollover. In this case, you will just answer "no" to the 2 questions about a Roth iRA. The default is a Traditional IRA assuming it was not converted to a Roth.
The box 1 amount will show as income on the summary screen because it is income, but not taxable income but when you do a preview of 1040, line 16a will have "ROLLOVER" but 16b (the taxable amount) should be zero.
