Since whatever you've entered can not possibly have been sent to the IRS yet, you have plenty of time to change everything in your tax file...including how you want to receive your refund.
There a major form changes needed before that final stimulus can be included in the tax forms, and that will stop all filings longer that expected. SO....just don't go thru step 3 in the filing process, and you'll be OK. You can back up and change things at will now, and restart the filing process later.
