I mailed my amendment July 12, 2020 is their anyway to check to see if the IRS received my paper copy?

You did not mail your amended return July 12, 2020. That's three weeks from now. Do you mean June 12?

If you did not mail your amended return with any kind of tracking, such as certified mail, there is no way right now to confirm that the IRS received it. A few months ago the IRS stopped processing mailed tax returns, including amended returns, because of the Covid-19 pandemic. They are just now starting to process them again, but they have limited staff and a huge backlog, so it will be a long time before your tax return is processed or any status information is available. An IRS spokesperson said last week that they have over 11 million pieces of mail that they haven't even opened.
