Hi, I literally filed my taxes yesterday and today I received a document from Acorns (account was closed). I know I have to amend, will this negatively impact me?

I called Acorns customer support and asked them if I was receiving any documents from them. I was told no. I figured since I had closed the account in early 2020 and literally made no money off of it that made sense. I filed my 2020 return yesterday, today I get a form from them.

As you can imagine I'm livid, but I'm also worried this will negatively impact me and I'll have to repay some of my already small return. Is there anything I should look for on the form (1099-DIV/B) to know if I'm heading for a smaller return?
