How to pay federal tax owed for 1040NR

[Le_nene]

I owe tax per the 1040NR I am filing for 2019. How can I pay this tax. The instructions for the form state that I can pay online or via direct transfer from a US bank and the like. But when I try to make the payment, I do not find the option for 1040NR (I find only 1040, or 1040-X, or 1040-SR). Should I just choose 1040, and hope that they will still associate this payment with my return (given all the information they obtain during payment, e.g. SSN).

Another point also has to do with filing. I will have to mail my federal tax return. The instructions ask to "enclose" payment with the return. What does this mean? Am I gonna get a receipt when I pay online and I should just print that with my federal return? What if I opt to do a bank transfer, will I still get a receipt?

In the old days, you paid by check when you mailed your return; this is still an option.

Right now IRS is not processing paper so your return and check will sit in a trailer in the IRS parking lot.

Your bank statement detail for the transaction using the online payment system is your receipt.

Your SSN or ITIN is associated with your payment; select 1040.
