What is the trouble?

Will not let me continue completing my information. To many try’s so I am logged out every time.

If your account has locked after too many attempts, I believe it will let you try again in an hour or so. 

There are a number of reasons for not being able to log in--multiple accounts, wrong User ID, wrong password, etc. 

You can have up to 5 accounts that use the same email address for notification purposes.  A User ID may be an email address, but it doesn't have to be.  It might be only part of an email address, or it can be anything at all.

To get a list of your User IDs and recover account access, reset password, etc., you can use the tool at the link below.  When you use the Account Recovery tool below, try using your phone number first.   After that, if necessary, then run the tool on your email address(es) you can access.

NOTE: Before running the account recovery tool below, log out of all Intuit accounts including this user forum, or you might end up in a loop.  Then clear your browser Internet cache, close your browser, then reopen it, and go to the link below.  You may wish to copy this link so you can paste it into the new browser session.

If still no luck after running that on your phone number and email address(es) that you can access,  here's another method:

Go back to the tool again, but this time leave the data field blank, and choose the small blue link that says "Try something else", and it will look you up by SSN and other parameters.

I forgot my password for 2018 turbo return 

I am attaching a link for your instructions to retrieve the password.

I keep getting a message that I need to update my browser however I already completed that but still won’t let me in. 
i’m very frustrated and I need to figure this out

Have you tried using a different browser. Sometimes, that's what it takes to resolve the issue.
