Retirement Savings Contribution Credit

Hi,

I pay into a 401(k) at work and my adjusted gross income is approximately $34,000. When I get to the section 'Retirement Savings Contribution Credit' in turbotax and try to open page for 'UPDATE' nothing happens. I have entered my information from my W2 for the 401k amount. Is this not a valid plan for this credit?

Thanks, Donna
