Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
How are you today.
According to the IRS "If you are a surviving spouse and you receive a tax refund check in both your name and your deceased spouse's name, you can have the check reissued in your name alone. Return the joint-name check marked “VOID” to your local IRS office or the service center where you mailed your return, along with a written request for reissuance of the refund check. A new check will be issued in your name and mailed to you."
I'm sorry to hear about your loss, by the way.
Thank you! Will do ......
