Hi, need help, accidentally put yes but answer is NO- Did you contribute to a qualified retirement plan in 2018? The system will not allow me to change !

If there is an amount in Box 12 of your W2 reporting contributions made through work to a retirement plan, the software is getting the information from that. 

If that is not your situation, and you need to get back to that section,

Sign into your account and your return

Click "Pick up where I left off" 

Click Federal on the left side bar

Click Deductions & Credits along the top

Scroll down to Retirement and Investments

Continue through that section.
