How to verify prior years unallowed loss in form 8582?

[mcw]

I know turbotax track this automatically for me since I am using turbotax all the way.

And I guess it adds up all my previous loss, not the last year's only. Is that right?

Where could I find the last few years loss? Is that shown on every years' form 8582?  I don't have previous years TT software to open every tax return.

Thanks

Yes, it adds to the accumulated loss. If you need to specifically see the loss from 2020, you will need to look at your 2020 Form 8582.

Thanks for your reply.

The amount matches to my 2020 Form 88582 when I first import it from the last year turbotax file, but later when I input my rental income, the amount increased. Are there other factors that could change the amount other than 2020 Form 8582?
