My intial return date has passed on 3/19/2019. This was the expected 3 week mark date. Now when i go to the "wheres my refund tool" all i get is "still being processed"

I'm curious why there is no actually bar or status anymore. When can i expect an update now that the 3 week mark has passed. And when can i expect me refund. From what i've reviewed there are no issues with me tax return. I'm assuming that this just means someone is manually reviewing my tax return now but i'm wondering how long that process takes as well.

Intial File Date: 2/23/19

Expected Return Date: 3/19/19
