CARES ACT RMD Rollover-Recording Form 1099R

I received my RMD on my IRA & under the CARES Act I rolled it over, returning the funds (including tax withholdings) back to my IRA.  I completed the Turbotax input showing the full amount taxable as shown on 1099R Box 2a, then marked a later section that there was a full rollover back to the IRA & Turbotax states the amount is not taxable. However, the amount isn't reducing the taxable amount to zero.  How should this be handled on the input?  Do I simply input the Box 2a taxable amount as zero for is there some other mechanism for doing this?

 

Thank you.
