How do I change my business code in Turbo Tax online. It is incorrect and the system does not show an edit option.

There "should'  be a blue "Edit" link, but for a very small number of people there may not be, and I don't know why.  See this image:

If you don't have the blue link there, here's how to phone TurboTax Customer Support for assistance.

Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days/week.

Also try this.  Look at my image and get a good idea "where" the Edit link would normally be.  Then try hovering your mouse pointer over it and see if you can find an "invisible" link, and/or try clicking in that area.   Perhaps there is a hidden link there but the wording isn't.  It may take some trial and error, but see if hovering or clicking in the area where the blue Edit is in my image does anything.
