Wrong Bank Account Information

I used TurboTax for the first time this year, most of my refund was sent through the mail to my address. However, the bank account information on TurboTax and the IRS is wrong (the last four digits do not match my personal ones) and it is affecting my stimulus check from the IRS. I don't know who's account this is or if it belongs to TurboTax. I would like to change this information but I can only do so through the IRS.gov and their customer service lines are down due to COVID-19 issues. Since TurboTax are the ones who sent this information to the IRS I would like some personal assistance in resolving this issue. Otherwise, my stimulus checks will continue going to this unknown bank account which is a frightening thought considering that I could really use this money that is supposed to be provided to me.
