@DeltonaBob Yes, TurboTax could be compiled for macOS 10.13.6 (High Sierra) using an older SDK so that the thousands of loyal customers could still use it. Unfortunately, Intuit decided not to do that. I think that that was an unwise decision.
Incidentally, yesterday I entered a comment in this forum addressing previous comments about running TurboTax 2020 on macOS versions earlier than Mojave. My comment was polite and respectful, but expressed disagreement with Intuit's decision. That comment is no longer visible. Does someone censor comments in this forum if they express disagreement with decisions that Intuit made? If my comment was deliberately removed, I request that it be reinstated. If it wasn't deliberately removed, then I'd like to report that there must be a bug that caused my comment to disappear.
