Maybe @IntuitBettyJo can get some feedback on Lacerte input in the 1040 for the S-Corp line 17AC. I believe it is link to what 17AC was in 2019, not what it is in 2020. 

It is POSSIBLY due to the fact the 1120S instructions are still in draft form.  The draft form says 17AC is "Code AC. Gross receipts for section 448(c) Use the gross receipts
amount to figure the business interest
expense you can deduct, if
applicable. See section 163(j) and the
Instructions for Form 8990 for details"

Lacerte is showing it as SE income.
