I assume that you are age 59½ or over. If you haven't already, you'll be receiving a code 7 2019 Form 1099-R with the IRA/SEP/SIMPLE box marked for the distribution from the traditional IRA. When you enter this Form 1099-R, indicate that you moved the money to another retirement account and that you rolled over the money. When asked to indicate the amount rolled over, indicate the amount moved back to the IRA, but not to exceed the amount originally distributed, shown in box 1 the Form 1099-R. TurboTax will include on line 4a of Form 1040 the amount distributed, but will exclude from line 4b the amount rolled back to the IRA. TurboTax will also include the word ROLLOVER next to the line.
If the 2019 Form 1099-SA that you already received has a taxable amount in box 2 and that amount was included in the amount transferred back to the traditional IRA, the box 2 amount represents a new, regular contribution to your traditional IRA and will be an excess contribution subject to penalty if you are ineligible to make that contribution.
