@IntuitGabi   I only need to be able to access lines 10 and 11 of the current [2023] rendition of Form 8864 to enter the K-1 flow through amount onto the Form 8864.  In ProSeries, the amounts that are to appear on Form 8864 are already correctly populating onto the correct line of Form 3800.

If ProSeries can add the Form 8864, or allow a pdf attachment Form 8864, it would eliminate a great many returns from having to be paper filed into the black hole of the IRS paper return processing department never to be seen or heard of again.  If we could efile these returns it would stop the deluge of computer generated IRS notices requesting that which they already possess. If these returns could be efiled I am certain that the IRS would be much obliged to Intuit.

Form 8864 is now available in Lacerte.  Please add it into ProSeries too.
