After you click and highlight the Schedule C you are linking too, can you scroll down and hit Continue or Done? Are you using the desktop, trying to link a 1099?
Thanks for replying, I had to connect a mouse to my laptop, then called an expert and shared the screen to go back and complete manually some numbers 🙂 ! It was solved, but it duplicated my taxes, so I needed to erase all and start all over, fortunately get it done today. My guess( totally ignorant in this matter) the glitchy system is unstable and you must have all written before you type in , try not to go back and correct, if you do it it still keep the info you had entered and it will duplicate forms, creating errors.Better erase all and start all over again , it will save you time, stress and frustration. Another lesson, help desk is not able to help, they have no access to troubleshooting or anything like that, tax expert call will give you a clue of what's going on.
