I no longer have a US bank account and I no longer reside in the States. What is the best option for me to receive my tax refund?

If you do not have a U.S. account, a check will be mailed to the address you provided on your tax return.

To help ensure your refund check is mailed to the correct mailing address, you should carefully review and follow the Name and Address section in the instructions to the corresponding Form 1040 or 1040NR in order to provide a complete and accurate address on your tax return. If you file Form 1040NR or Form 1040NR-EZ, you have the option of providing an alternative mailing address outside the United States for the refund check.

If you move or change the physical address where a paper check will be mailed, make sure you file Form 8822, Change of Address.

To check the status of your refund, go to Where’s My Refund. If the response indicates that your refund checked was mailed, but you do not receive it within 45 days after the mailing date, call the International Taxpayer Service Call Center by phone or fax. The International Call Center is operational Monday through Friday, from 6:00 a.m. to 11:00 p.m. (Eastern Time). The telephone number (not toll-free) is 267-941-1000. The fax number (not toll-free) is 681-247-3101.

check, maybe debit card or apply the overpayment to next year and reduce 2021 withholding or estimated tax payments accordingly. 

check could take 2 months or more and you'll need a bank a/c that will accept your manual deposit. 

TurboTax may also offer to deposit it to a prepaid debit card (there are fees).
