Reversed a RMD due to Cares Act but still showing it as taxable

After withdrawing my 2020 RMD the CARES Act allowed me to roll it back into the same account with no tax consequences.  TT confirmed "you won't have to pay tax on your $10,000 rollover....." yet the Form 1040 is showing the $10,000 as income and taxable!  How can I get this corrected?  Many thanks.
