Retirement tax questions

How can I enter information into TurboTax so that it accepts my $8,000 Roth IRA contribution?  Quoting from the program after I entered my data:    "Your modified adjusted gross income is $376,341, which puts you over the current Roth limit of $240,000. That means the $8000 you put into a Roth is considered an excess contribution." 

Have I missed telling the program that the high MAGI is due to the amount that I converted?
