Edit Schedule E and Schedule A // Prorate Mortgage Insurance and Property Tax for 90 Day Part of Home Room Rental

Help please! I rented a room in my primary residence for 90 days in 2021 and then converted it to personal use. I have gotten lost in this community trying to figure out first on the online Premier version of TurboTax and now on the desktop Mac version:

  • Is Turbotax capable of calculating this so the right amounts are shown on Schedule E and Schedule A? It currently appears that TurboTax is not considering both the percentage of my home rented (25%) and the amount of time (24.6% of year). Based on the numbers on Schedule E and Schedule A, I think it is prorating time, the 24.6% only.
  • Can I edit the direct entries on Schedule E and Schedule A? I am trying to do this in Forms mode and it does not allow me to right click to edit as I have read in other instructions.
  • What are the specific easy steps I need to take so that the right proportions are deducted in Schedule E and Schedule A?

Thank you for any help! I spent more than an hour on the phone with two different TurboTax support specialists and they kept trying to make me buy the most expensive version of their product which makes me think TurboTax cannot file for this use case correctly without someone on their side editing the forms. I would love to be proved wrong!
