Turbotax can not and doesn't have the ability to contact the IRS on your behalf. the reference to schedule H is because it's a generic form that covers both schedule H and SE though a taxpayer may have 1 but not the other
look at schedule SE line 26. this is the amount deferred. this carries to schedule 3 line 12e not schedule C line 12e. we can't see the letter. actually, the payment for 21 (50%) was deferred until 1/3/2022 and for 22 (505) until 1/3/24. for further assistance try contacting Turbotax support
