Pennsylvania return can't be filed electronically with Federal K-1

I filed 4 K-1's LLC on my Federal return using TT Deluxe with no problem. When I went to do my Pennsylvania return all the K-1's were transferred over properly, when I did the review I received 1 error and it was as follows "Federal Schedules K-1 cannot be used to prepare electronically filed returns (unless it is a publicly traded partnership) these rules are set by the Pennsylvania Department of Revenue.

I have always filed PA and Federal electronically and never had an issue. Did something change in 2019 to have me printout my PA return and mail in? Thanks.
