How do I amend my 2020 taxes ? I entered the stimulus amount on line 30. And where's my w-2s?

TurboTax does  not keep a copy of your W2 forms.   

 

You will either have to contact your employer to request a copy or get a tax return transcript from the IRS:

Transcript

• You can get a wage and income transcript, containing the Federal tax information your employer reported to the Social Security Administration (SSA), by visiting our Get Your Tax Record page. Refer to Transcript Types and Ways to Order Them and About Tax Transcripts for more information.
• You can also use Form 4506-T, Request for Transcript of Tax Return. Check the box for Form W-2, specify which tax year(s) you need, and mail or fax the completed form. Most requests will be processed within 10 business days from the IRS received date.
   

IRS Transcript or Copy of Form W2

 

Did you file an original 2020 tax return?  Did you forget to enter your W-2's when you filed?   If you entered them when you filed the original 2020 return you do not have to "find" them now---the information is already there in Federal>Wages & Income.   If you forgot to enter a W-2 when you filed, that is a different story and you need to get a copy of the W-2 from your employer.   

 

Are you only amending to seek the recovery rebate credit?   Could someone else claim you as a dependent for 2020?  If so, you have not become eligible for the credit now in 2024.  Getting that credit is based on your circumstances in 2020.   

 

I am concerned that you posted your question from a current online version of the software.  Are you actually working from your own original 2020 return in order to amend and prepare a 1040X to make changes to a 2020 return that you filed?
