I had started a thread about a different symptom of this new 2020 behavior:

Someone finally pointed me to this thread as the root cause.
Another impact of this change is that if you import transactions from a brokerage (or TXF file), for each transaction which lists amounts in cents (other than an even dollar amount), TurboTax creates a capital g/l adj form. This results in an enormous amount of clutter in the Forms list, and for my tax return bloats the printout of the "Recommended for your records" return from about 150 pages to over 3000 pages (with 2 pages for each capital g/l adj form, even though this form shows no adjustments.
Also, I did get some errors for < $0.50 wash sales, since it rounds them down to zero but then gets an error saying that a wash sale can't be for $0. Not clear what the best way to correct this is.
