Depending on the age of your children, that might be too much saved dedicated to education. A 10 year old could have around $150,000 for college if you start at $75,000. That is about double a state education.
Still, if that is where you want the money to go, CT also allows a 5 year carry forward, meaning you can put the next 5 years of contributions in there now and get the next 5 years of deductions later. That would eat $120,000 now (10k each child for this year plus the 5 carry forward years).
Almostrtrd has a good point regarding 529's FAFSA. IRA accounts are not considered for FAFSA. Are you maxing out all of your 401k/IRA/ROTH accounts for you and your spouse?
