I did not prepay tax, no refund coming, but still want the irs to get my direct deposit info for the covid stimulus. will turbotax still take and forward my bank info?

i know about the irs portal, but it's not working yet. i thought  to file my 2018 tax here, but would only bother if i'm sure they'll get my bank's account & routing for the covid stimulus so i don't have to wait months for a paper check.
