Thank you, Dana! You helped me sort our my 2018 and 2019 tax situation.
Just one more question...I have the exact same problem for 2020, my 2019 basis is wrong, which I'm going to file amendment. Now I'm about to file my 2020 tax, should I use the wrong basis on the existing 2019 tax return? Or can I use the correct basis for my 2020 return, while filing for my 2019 amendment? (let's say I file my 2019 amendment today, and file 2020 tax return a few days later)? I'm trying to avoid the need to file another 2020 amendment down the road, when I already know there is a mistake in it. Thank you very much!
