How was your 2018 return prepared last year--in Online TurboTax or desktop software (CD/download)? If you used desktop software last year, the info won't automatically appear in a 2019 online return. If you DID use 2018 desktop software, we can tell you how to transfer the *.tax2018 data file into a new online 2019 return.
You appear to be using Online Self-Employed Edition now. If you used Online TurboTax for 2018, and again now for 2019, it should have transferred the 2018 info in automatically when you started the 2019 return--if you are in the same account. So, if it didn't transfer in, it makes me wonder if you are in the correct account; i.e., the same account as last year. Do you see evidence of the 2018 return in that account you are using? Did everything else except the rental property information transfer in? i.e., did your name, SSN, DOB, address, other income items, etc. all transfer in from 2018?
If you used Online TurboTax for both 2018 and 2019, but see no evidence of the 2018 return in that account, we can tell you how to look for multiple accounts.
ADDENDUM: I'll go ahead and tell you how in my next comment below, just in case you need it.
