My taxes were accepted 17 days ago, then I got code 152, now it says they are being processed. Can they still be rejected at this point

And does the this holiday weekend count towards my 21 days?

Tax Topic 152 is generic payout information generally seen if you have chosen direct deposit of your funds.  Your message simply means you are being processed. They can't be unaccepted. 

The 21 days are business days, Monday through Friday.
