Stimulus check amount incorrect

I can't seem to find any answers on this question, and the IRS is understandably inaccessible, so I thought I'd ask here. I filed our taxes shortly before everything started locking down, but not soon enough before things got crazy, and so our tax return has been delayed in processing. It's been about a month or so. We had a child last year. She was included on our 2019 return, but because that return hasn't been processed yet, our stimulus check (or EBT rather) was sent for the wrong amount, less $500. I'm not sure if I'm just out that money or if there's a possibility that I'll be able to claim it later on, after the IRS reopens to take inbound calls. Anyone have a clue? I'm guessing I'm just going to have to wait until the IRS reopens, but maybe someone out there can point me to a source if they know any additional information.

 

Cheers,
