That makes sense, but to manually enter the correct number, I need to modify the value in column 10 of Form 2106, which is a "read-only" field. Is there a way to make it editable?
You can't include form 2106 with your tax return. The deduction for work-related expenses was eliminated in 2018 and forward, except for certain military personnel and qualified performing artists. If you enter your expenses in form 2106, they won't be reported on your federal tax return because they aren't allowed. You can print out and use a copy of form 2106 if that is convenient to figure your deductible expenses, but the only thing you enter in Turbotax is the adjusted expense amount on line 5c of the schedule SE adjustment worksheet. The IRS instructions for clergy say to keep a copy of your calculations in case they want to see them, but it does not have to be on form 2016.
There are some states that still follow the pre-2018 tax rules and allow a state itemized deduction of work-related expenses. In that case, you would use the work expense interview in turbotax, even though the federal form 2106 won't be filed. There are two ways you could use this interview to report your expenses.
1. Just report a percentage of everything. If your deductible percentage is 60%, you would enter 60% of your mileage and 60% of your other expenses -- do the adjustment before the interview and enter the adjusted numbers, rather than enter the real numbers and adjusting them later.
2. Or, you can perform an override on the tax form in Turbotax Desktop by switching to Forms mode. I don't know where to tell you to make the override. It might be on a different worksheet, or it might be directly on your state's version of Schedule A. However, tax forms with overrides can't be e-filed (IRS rule) so you would have to print and mail your return. And overrides may void the 100% accurate calculation guarantee.
(Some places allow you to enter numbers, like line 5c, because they do not disturb the calculations on the worksheets, just provide extra information. An override blocks the calculation and substitutes your answer. That's why a manual entry on line 5c of the worksheet does not block e-filing, but overriding the calculated deduction on your state return does block e-filing.)
