Can you please clarify exactly what you require assistance with? 

I filed my taxes wrong and now my taxes are just pending

Ok, if you need to make corrections to your return, you can amend it, but please explain why you feel that you filed incorrectly? Is there something specific you require assistance with?

I wouldn’t know how exactly to do that and if I did already it wouldn’t let me amend them why is that?

You will not be able to amend your tax return until it has been accepted by the IRS.  Please see the below FAQ for more information on amending a 2019 tax return:
