The IRS is not working on mailed returns now---and an amended return can only be filed by mailing it in. Under normal circumstances you would be able to see something about your mailed in Form 1040X after about three weeks, but that is not the case right now. The usual 4 months for processing an amended return is going to take longer. Sorry.
Per the IRS website IRS Operations During COVID-19: Mission-critical functions continue: The IRS is not currently able to process individual paper tax returns. If you already have filed via paper but it has not yet been processed, do not file a second tax return or write to the IRS to inquire about the status of your return or your economic impact payment. Paper returns will be processed once processing centers are able to reopen.
If you mail a tax return (or a payment) to the IRS, it is a good idea to use a mailing service that will track it like UPS or certified mail so you will know it was received.
TurboTax will not know anything about your amended return, and nor will TT know that you put your 1040X in an envelope and took it to a mailbox. TurboTax does not get updates on mailed (or e-filed) returns.
When the IRS finally opens its mail and begins to process mailed returns you can check the status on the IRS site.
The status of the mailed amended federal tax return, Form 1040X, will be on the IRS website for amended tax returns - https://www.irs.gov/filing/wheres-my-amended-return
However, the IRS is not processing any type of paper tax returns at this time.

The IRS is currently not processing any mailed returns (regular or amended) and hasn't been for some time. An amended return in normal times takes 16 weeks to process and will take a lot longer with this pause in processing. The IRS has not indicated when they will start processing mailed returns again. It is too soon to worry about the status of your return.
When they do start processing it, you can track the status using this tracking web site:
In normal times it takes up to 16 weeks or more to process an Amended 1040X return. But these are not normal times.
Sorry the IRS has limited staff due to Covid-19. They just started opening the mail in June that's been stacking up. Back in March the IRS closed their processing centers and stopped processing mailed tax returns. An IRS spokesperson recently said that they have about 11 million pieces of unopened mail. The IRS says....."We’re experiencing delays in processing paper tax returns due to limited staffing. If you already filed a paper return, we will process it in the order we received it." So it may take longer if you mailed in June or later. So you have to keep waiting.

Then once they start opening the mail, After 3 weeks you can track it here,
i mailed my amended return in mid July and just yesterday I checked status on where's my amended return and it showed me they received it july 20th. Due to Covid system was not being updated frequently. I called IRS myself and they said to check my status again in 3 weeks.
