Form 8582 Never Generated

I am an active participant for a rental property I own.  Form 8582 did not produce in 2019 because I used the property for personal use more than 10% of the allowed time.  Total expenses were limited to income received.  In 2020, because 8582 did not get filed in 2019, the prior years unallowed losses from 2018 of over $160,000 (line 1c) were all lost.  Should I actually lose all of those losses because of the 10% personal use in 2019?  Or can I amend my 2020 return and restore the 8582 1c prior year losses from 2018?  Thank you for your help with this issue.
