Is it Ok to mail 2019 Amemnded Returns 1040X & 140X now? How do I find out if my original mailed return has been processed?

I had mailed my original 2019 returns (No refunds or payments due). I understand IRS has suspended processing mailed returns. How/where do I find out if my return has been processed? Is it Ok to mail my 2019 Amended Returns 1040X & 140X now?

Thank you.
