The other unit, I used it for rental in 2018, lived in it around 6 months in the 2019 and rented it again.
On this unit, did you just leave it classified as a rental for the entire year and claim 6 months of personal use? Or did you convert it to personal use for six months, then back to a rental?
Here's what we need from your 2019 tax return, so we can manually enter the depreciation history in the 2020 return.
For each rental property listed, there are two IRS Form 4562's in the 2019 PDF file. One is titled "Depreciation and Amortization Report" (and will most likely be the one needed most) and the other is titled "Alternative Minimum Tax Depreication". Both forms print in landscape format. So with two rentals you should have 4 of these forms.
If you had any carry over losses in 2019, then you'll also need the IRS Form 8582 from the 2019 return. WIth the changes in tax law in 2018, it's perfectly possible you won't have any carry over losses. So if the form 8582 is not present in the 2019 PDF, that's fine.
Can you go ahead and print out those 4562's and the 8582 if applicable? Trying to do this with the forms open on the screen while the TTX program is open is to much of a PITA. Simpler if you just print out the forms. In the print dialog just select to print the page currently being displayed in the Adobe Reader program, and that way you don't waste paper.
