Undoing an RMD in 2020 per Cares Act

We started our 2020 RMD distribution early in 2020, but the CARES Act obviated the necessity for doing so.  Our financial advisor returned the money back into our IRA,  less the state and federal tax withholding amounts (which could not be recouped).  According to online advisors, we are told to report the total amount of the RMD on line 4a and then put $0.0 on line 4b for "taxable amount" AND write the word "Rollover" in the margin.  TurboTax doe not appear to allow this option...is there a way around it, short of filing a paper copy? Appreciate advice!
