Welcome, and thank you for posting here in the Roku Community, @bennyguzman!
No worries. We're here to further assist you in accessing the Freevee app using your Amazon account.
Firstly, you don't need an account to stream on the FreeVee app but if you are prompted on the 'Sign in' page (with no option to skip) and mentioning you already have an Amazon account, try using those credentials to sign in to FreeVee.
Let us know how it goes and we'll go from there. Hope it helps!
Best regards,
Carly
