Sorry to be all "I heard this one weird trick from a friend and it really works" BUT, after weeks of not being able to see our status on the IRS website, we tried typing our address in ALL CAPS and it worked and we were able to finally enter our bank account info.

The IRS website is built on a really old mainframe and apparently can't read lowercase letters. So instead of "123 Main Street, Anywhere, USA" try "123 MAIN STREET, ANYWHERE, USA"

Also, as a friend pointed out, there was a big IRS system upgrade a few days ago - it might be that the site only just ported over your info and would be working either way. But we tried lowercase again and it didn't work, and then upper-case and it did. https://www.usatoday.com/story/money/2020/04/24/troubled-irs-tool-get-critical-system-updates/3019313001/
