The IRS accepted my refund on February 12, 2021.  

 My  Return had been  changed , BY THE IRS and I have been trying to contact them since April  5th when I when I got notification .  They stated I had a mathematical error stating that I had claimed someone I didn't and I didn't have any dependants6 on my return.  The irs changed my to A $0 amount and now I can't get anyone to speak with me.
