If you prepared the return, enter the address info exactly as it is on the 1040, if not, use ALL Capitals , make sure you are putting the DOB as xx/xx/xxxx and no spaces or dashes in the SS.

If that fails, and you have someone else that you trust, let them put the info in. Sometimes we enter a wrong number and our brain does not let us see the mistake & we keep making it. I had many clients asking how I found their info when they couldn't, and data entry accuracy is the only reason.

If that doesn't work then you're on hold till they figure it out, or the check just shows up. The IRS has just assigned 3500 employees to a dedicated EIP phone line but who knows how long it will take to get thru.
