Investors & landlords

Thank you @Carl. I think I have it set up right now. I have another question if you don't mind answering.
To recap:

I lived in a 3 bedroom home in 2022 and was renting out part of my home. I put 3 different rental assets on Schedule E, one for each Bedroom (A, B, C).  I allotted proper percentages (sum for all 3 bedrooms = 100%)  in order to capture the correct depreciation and I manually did the prorated calculations for rental specific expenses (repairs, supplies, maintenance etc.)

1. Bedroom 1 was rented from January-December (full year) 

2. Bedroom 2 was rented from July-December (6 months) 

3. I lived in bedroom 3 (Master) from January-November(11 months), then moved out and started renting the 3rd bedroom in December of 2022. So, the whole property was rented by Dec 1, 2022 to 3 separate tenants.


My question:
I had a major shower leak in the master bedroom that I occupied at the time in February 2022. It leaked into the downstairs shared common areas with my tenant. The repair/improvement(?) was completed by May 2022. I spent a total of $6,500 on the shower repair which entailed demoing tile, installing a new shower pan, replacing rotted subfloor and joist portions and retiling. The breakdown was $2000 in materials, $1000 for a Plumber, $500 for a Carpenter, and $3000 for a Tiler.  Should I factor in the $6500 into the cost basis of the property specifically for my Schedule E entry for Bedroom 3 (master)? What about the other bedrooms?
Can I expense a portion of the cost of this repair/improvement(?) as part of the De Minimis safe harbor?

Thank you in advance.
