My refund, all stimulus' got accepted Feb 16th, it's now Apr 20th IRS website has been saying it's been accepted a date will become available when there's one any help?

All you can do now is, wait. At least you know that the IRS has your filing. It does not matter who sent your 1040 to the IRS. The IRS is the sole destination for tax returns. No one has discovered a way to make the IRS speed up sending out refunds. No one ever will because the IRS is an overwhelmed, over worked, under funded and under staffed government bureaucracy. Eventually you will get the pay off of your no interest loan to the government.

Have you thought of paying just enough by estimates or withholding to avoid a penalty and let the government wait for your check?
