Here is some additional information for my question.
I went back to TurboTax for my 2019 tax return (TurboTax Deluxe Desktop) and entered fake Schedule K-1 values that were similar to the values on the Schedule K-1 I received for 2020.
Then I had TurboTax print the pages required for filing this return to a pdf file. Just as with my 2020 return, the values from the fake Schedule K-1 were shown in Form 1040 Schedule 1, Line 22 and Form 1040 Schedule D, Line 12 for the 2019 return.
TurboTax also prepared a Schedule E, Page 2 for the fake trust with the only entry on Schedule E being a line in Part III with the trust’s Name and its EIN.
There were no pages in the material that TurboTax prepared for filing this fake 2019 return that purported to be a “Federal K-1 Trust” form.
