      > you are not related to the pther party

•  you do not have the same principal abode as the other party for more than ½ the tax year.  Temporary absences like for school are ignored
• If you are not a full-time student you're over 19 at year end or if a full-time student over 24   
• the other party hasn't provided over ½ your support
•  

or as you are not a qualifying relative becuase

• your gross income for 2019 is over $4,200 or
• you provided over ½ your support or
• your not related or did not related lived less than the entire year with the other party

you can claim yourself

you will need to paper file

the IRS will send both you and the other party a request to amend 

if neither does the IRS sends a second letter asking for proof

I am not related to the party that listed me and I want to amend this. What are the steps I can follow?

You can't dispute it and you can't amend it. You can only file a competing tax return. The IRS will straighten it out*. 

You may have to wait a year for your stimulus payment. When you file your  2020 return in 2021, you will have the opportunity to report the amount of the stimulus check(s) you did receive, and if it was less (including not getting any) than what you were entitled to, you will receive a credit on your 2020 tax return.

*If someone else claimed you, as a dependent,  inappropriately, and if they file first, your return will be rejected if e-filed. You would then need to file a return on paper, claiming yourself, if appropriate. The IRS will process your return and send you your refund, in the normal time. Shortly (up to a year) thereafter, you’ll receive a letter from the IRS, stating that your exemption was claimed on another return. It will tell you that if you made a mistake to file an amended return and if you didn't make a mistake to do nothing. The other party will get the same letter you did. If one of you doesn't file an amended return, unclaiming the exemption, the next letter, from the IRS, will require you to provide proof. Be sure to reply in a timely manner.

Winner gets the tax benefits; loser gets to pay the IRS back with penalties and interest.
