IRA

My 1099R gross distribution shows $19,950  -taxable amount not determined

$16,800 was 'rollover' due to covid provisions 

$3,150 was QCD qualified charitable distributions paid directly from IRA to qualifying charities

Therefore  taxable amount should be $0.   However, when putting $0 in the taxable amount on the IRA worksheet, it comes back repeatedly for review and will not allow me to efile my returns.  Please help!! and how should I report this.
