Deductions & credits

I believe there are multiple bugs in the 1116 Worksheet and the 1116 itself.  I have e-filed my 2020 Form1040 twice.  The first time i fixed the missing entry on the 1116 that TT said was missing,  Filed the second time rejected, again 1116 error.  This time no error was noted.  I have run final review, and Errors multiple times, each time they come back as "Return has no Errors" or Return is ready to E-file.  The same think happened last year, but then i was also using TT Professional and with the same entries i was able to e-file.  So i do believe the 1116 has multiple bugs in the Turbo Tax Deluxe Edition
