A mailed tax return cannot be tracked until the IRS starts processing it. There are stacks of unopened mailed tax returns sitting at regional offices waiting for processing to start on them. The IRS has not indicated how soon they will be able to work through the backlog.

If you included payment instructions on your tax return, just wait until the IRS processes it and takes the payment from your account.
If you did not include payment instructions on your tax return, you can use a voucher that TurtoTax prints to mail in with your payment or you can use IRS direct pay to make a payment: https://directpay.irs.gov/directpay/payment?execution=e1s1
