Scroll through the other posts, its been talked about in here...someone found a workaround that may work for you....I don't have any farm returns so I cant help, sorry.

This workaround worked.  I entered the description in Box H of the Schedule 1 Line 36 smart worksheet as "Form 8903/Form 1099-PATR Box 6" and the return was accepted for efile.  

So prepare the Form 8903 manually to report the amount from Form 1099-PATR Box 6 and save it on your computer somewhere. (I created a special folder called "Proseries PDF Attachments" to park all of these in).  Enter the amount from Form 8903 in Box H of the Schedule 1 Line 36 smart worksheet.  Don't use any description in Box H that has "DPAD" in it.  Attach the Form 8903 to the return before transmitting.

When will the Form 1099-PATR return to ProSeries for posting the data? Had it in 2018 or 2019. The 199A issue is getting more prevalent and needs to be more computer driven than preparer search and find driven.
