You have a mess on your hands and unfortunately I also recommend that you meet with a tax professional who can help you through this.
You have penalties of $2,460 for 2019 alone assuming that you are the only shareholder.
You also have penalties accruing for 2020 assuming you did not file for an extension in March. So 2020 penalties are now $410 through the end of April and $205 per month or part of a month; maxed out at 12 months.
Spend the $$ to get this fixed so you do not have the IRS sending you letters.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
