How to enter a sale of rental property (prior primary residence) when no other primary residence owned.

Sorry if this is repetitive question, but I find some conflicting information here.

I lived in my ONLY primary residence for 10 years, then moved out and turned the house into rental. I did not purchase another home. After 10 more years of renting it (I didn't live in my primary house at that time), I sold the house last year. 

Should I report in TT this sale as my primary residence or as a rental property?

 

Thank you in advance!
