2020 Indiana Form IT-65, Line 8, Total Amount of Pass Through WIthholding requires we "enclose IN K-1 from paying entity."  The ProSeries E-File tab does not allow attachments.  How are we to comply with the Indiana requirement to submit IN K-1 supporting the pass-through withholding?  If you fail to attach the form, Indiana will probably deny the withholding credit to the chain of investor partners and ultimately their members.  This would result in a very time consuming effort to get Indiana to allow the withholding passed through.
