Deductions & credits

It is not a commonly used  form ... if you only have to go back to 2017 you could just amend 2017 & 2018 then do the 2019 return correctly ... it is not the correct way but the IRS will probably allow it.   

 

Or you could get the form & instructions from the IRS and try it yourself.   

 

OR you can call around to local pros and ask them if they use the DRAKE program as that form is part of that program so it makes it easier to complete.
