Programming can mean either Intuit, or IRS.

IRS tells software companies how to program for returns to be accepted for e-filing. That's policy, not software.

On another list-serve, someone posted that the IRS will be scrutinizing returns using 2019 amounts for EIC veddy, veddy, veddy carefully (which translates to holding up those refunds).

Well, that settles it then.  Someone on a listserv is always right.  I bet they even called it a "red flag."
