After you file

I went through the same thing, got a 45 day letter,  the next week got a 60 day letter, checked my bank account the next Friday  on 4/5/19 and my refund was  there, my wmr finally  updated with a DDD but I stopped  checking it  so I never seen it. So you may not necessarily have to wait  the whole time, just when  they  get to it I guess. Best of luck, very stressful this year
