Hi,
It's a bug, and has to be fixed. Tax day is approaching, and users need to be able to enter their data, and finish their taxes.
Regarding the "Supporting Details from previous year" argument: I've been using TTx since 1996 always install from CD, and always import my previous year tax return with all its supporting details, and never had an issue. Actually, I reuse my previous year's supporting details. Btw, other fields that also have supporting details allow keyboard input without issues. Some fields do not, so this year there's an issue with some input boxes not accepting input
