There is a problem when renting out "a part of" your home. Chances are high the depreciation figured for that first year will be wrong. When (not if) that happens let me know and I'll show you how to fix it so that you can still e-file.
To confirm the correct depreciation amount for the first year, use the MACRS worksheet on page 36 of IRS Publication 946 at https://www.irs.gov/pub/irs-pdf/p946.pdf For line 6 of the worksheet, use Table A-6 on page 71.
