Overstated Capital Gains on Sale of Rental Property

Wondering if anyone else using TurboTax Premier has had issues with TurboTax overstating the capital gains on rental property. I purchased my home in 2017 for $199,999 lived in it for 10 years, rented it for 5, and sold it last year for $300,000. We depreciated $20,000 in the 5 years we rented the property for. We sold in year 6 after completing some repairs. TurboTax is showing $204,000 capital gains (these are my only capital gains). I traced the calculations and it appears the costs basis for the home that is being used does not agree with the actual costs basis. Contacting someone at TurboTax has been a series of waiting, automated call backs, and transfers. Any help or ideas will be appreciated.
