Amending 2019 State return.

I made a minor mistake in my 2019 State return and I need it corrected in order to keep my job. I made "Employee Business Expenses" $1,000 when it should have been $0. I have already downloaded TurboTax 2019 software to amend the tax return. Please help me. Once i get to the "youre almost finish" the continue button no longer works. How can i amend this error?
