Writing-in an "Above the line" deduction on Schedule 1 in Turbo Tax on form 1040 (tax year 2019)

[Rwg215]

How do I write in an "above the line" deduction on Form 1040, Schedule 1, line 22 in Turbo Tax? 

The IRS official instructions for Line 22 of  form 1040, on page 90 concerning "write-in" deductions say:

"Include in the total on line 22 any of the
following write-in adjustments. To find
out if you can take the deduction, see the
form or publication indicated. On the
dotted line next to line 22, enter the
amount of your deduction and identify it
as indicated."

The publication then goes on to list various "above the line" write-in deductions and the abbreviated codes to use to identify them.  However, How can I write-in above the line deduction/adjustment be entered into Turbo Tax and have Turbo Tax calculate the new write-in deduction/adjustment?

Thanks.
