Why does turbo tax require that my 529 account number start with a "55" or 57"? Mine starts with "83"

I entered a 529 account contribution to a TurboTax test account but I was not asked to enter an account number in regards to a 529 contribution.

• Are you entering a contribution or are you entering a 1099-Q?
• What screen are you asked for an account number?

Pennsylvania allows a maximum deduction of $15,000 per beneficiary, per taxpayer for 529 Tuition Account Program contributions made in 2021 to a Pennsylvania 529 Tuition Account Program or another state's 529 College Savings Plan.

• Rollovers are not considered a contribution, and you are not allowed a deduction for any amounts you rolled over.
