2016 taxes did not get filed. I found out HR block didn't send it in. What do I do to file those taxes

You can no longer e-file a 2016 tax return.  It has to be printed, signed and mailed.  If you are getting a refund, it will be OK to file past the deadline; you will not be penalized.  However, if you owe tax due, get your return filed ASAP, as penalties have begun to accrue.

Do you mean you used a tax prep service at a brick and mortar H & R Block that neglected to submit your tax return, or did you use their software?

I would go back to HRB, and have them make it right.
