State tax filing

I am unable to complete my request to file my federal and state taxes and request my federal refund be used to buy I bonds. I navigate to the page where I enter the amount of the I bonds I want to buy, and the name, and also I am able to enter on a following page the account info for direct deposit for the state refund, and then the website kicks me back to the page I started at, asking if I want to file and split the federal refund to I bonds and deposit. This has been going on for two weeks now, I have called three times and spoke to the Live tax advisors who are unable to help but assure me that the issue will be fixed within 'days'. Help. I have already paid Turbo Tax fees and now am unable to proceed to file.
