After you file

I had a tax pro e-file my 2018 & 2019 taxes filed both on 2/5/20 received 2019 on 2/17/20 I have seen people post in here that you can't e file back years returns that's false you can haven't heard anything about 2018 return of course due to the IRS only focusing on the stimulus money when the "get my payment" first opend it said my stimulus was deposited into a bank account with the last four of the account actually being the last four digits of my social security number so I was confused then this weekend when they updated the website it says now check to be mailed 5/1/20 and I seen people post on here they had the same message there check would be mailed last Friday on 4/28/20 and they actually received them that day or the day before so if anyone in here has a mailed check date for tomorrow 5/1/20 PLEASE POST if or when y'all get them thanks
