Did you ever get yours? I'm having the same problem, my refund tracker says the irs has approved my return and it will be sent to my bank on for before 2/26/2020 but the sent bar is still empty and I have no refund deposit in my account. I'm starting to worry because never in all these years have I not gotten my return the morning of the date I was given, everything is the same, my bank info is the same, my filing status, my dependents, no changes. It seems like more and more people have problems as the years pass. I filed 1/30, accepted within 15 minutes. I NEVER wait this long or have hold ups. I see you commented on the 11th, when did you finally get yours? If you've even gotten it yet.
