I filed 2/1/19 still haven't received my taxes after identify myself do all taxes have to b given out by April 15 the

No they do not. You can track and get an update on your return by using the source below. Also if it has been more than 21 days since your returns were accepted you can contact the IRS directly. That is provided also on how to contact them.

If you were required to verify your identity, it typically takes about nine weeks after that to receive your refund.  And no, refunds are not required to be issued by April 15.  April 15, 2019 is the date of the tax return filing deadline.  That is when people are supposed to have their Form 1040's submitted to the IRS.
