After you file

I recently read the updated guidelines for this stimulus in relation to 2019 taxes. According to the article, If your 2019 tax return is still being processed, they are suppose to derive your payment from the 2018 return. I have a few friend that have received their check but not their refund and they have their return still processing. With that being said, I would like to know why we haven't received this yet. Regardless of the reason, all Im asking for is a little communication from them in this regard.
