Investors & landlords

How do I enter the results for my Cost Segregation Study in TT? I purchased a vacation rental in 2019 so this is a new set up and I do not want to ONLY utilize the straight line 27.5 yr deprecation. I also want to use accelerated deprecation. Also, my property management company entered Gross Rents in Box 3 of my 1099-MISC they sent me and TT does not allow that entry. Do I just enter my Box 3 amounts in TT's Box 1? Please help!
