Well, now my 2020 desktop clients have lost their mapping as well.  I can understand re-mapping all accounts when we had the switch to the 1099-NEC form, but why will our account mapping not hold from year to year now?  We need a fix! And yes, I have updated my QB (running R15_54, which is newer than the one listed on intuit for 2020 desktop) and my payroll (running table version 22216). Yes, I have verified and rebuilt my QB.
