I would like to know if my amended tax return has been accepted. I’ve tried the IRS website but it gives me an error message.

Amended returns do not get a notice that they are accepted or rejected.  Hopefully, you mailed in your amended return.  Amended returns must be mailed.

Three weeks after mailing your amended return, you can start tracking it at the IRS Where's My Amended Return? tracking tool.  Please allow at least 16 weeks for the IRS to process your amended return.

Processing times for amended state returns vary from state to state. If it's been more than 12 weeks since you mailed your amended state return, and you haven't heard anything, we suggest you contact your state tax agency.

Amended returns don't get Accepted or Rejected since you have to print and mail it.  It can take them 16 weeks for the IRS to process them.  And they only mail checks for refunds.   After 3 weeks you can track it here,    https://www.irs.gov/filing/individuals/amended-returns-form-1040-x-/wheres-my-amended-return-1
