From reading through this tread to see if I can help, it's become apparent to me that you are clueless. Hey, it's not like you learn this stuff through osmosis.
If you left the company in 2019 then you "should" have been issued a final K-1 which you will require before you can even start your personal 1040 tax return. I would highly suggest you seek professional help yesterday, if not sooner. This is especially important if your state taxes personal income. Doing things wrong, or not doing them at all will cost you dearly in the way of fines, penalties and back taxes. That would make the cost of professional help seem like a pittance in comparison. So please seek professional help for the sake of your wallet.
