Investors & landlords

I did not set it up correctly.  I started renting it in 2022.  I used TurboTax.   I bought the download version from Costco both years.  I haven't filed yet for this year.  I left the date placed in service blank for this year.  Last year I had the original purchase date -1988- still listed.  Do I need to do an amended return for 2022? Is there a special form?  Is it placed in service when we bought it, moved out or when tenants actually moved in?
