Received erroneous 1099-NEC tax form

I received a 1099-NEC tax form by FusionCash saying I made over $700 in 2021 but I haven't logged in their site for over 10 years and made no money since then.  I emailed their website support from my account and got no response.  I also snail-mailed the company address with no reply either. What am I suppose to do? Contact the IRS about this? Or should I include this in my tax return? Or should I ignore it?
