This error appears when I run state review (see screenshot)

Here are some excerpts from the letter that the program manager (TIAA-CREF) send to accountholders:
When Bright Start 529 transitoned to a new program manager on September 30, 2024, account holders were
assigned new account numbers. As such, each Bright Start 529 account that was open prior to September 27,
2024, has a minimum of two account numbers associated with it during the 2024 calendar year:
1. A 9-digit numeric account number valid through September 27, 2024
2. An 11-digit alphanumeric account number valid from September 30, 2024, onward
For the 2024 tax year only, taxpayers who made contributons to their Bright Start 529 account both before
and afer September 27, 2024, will need to enter the account number valid through September 27, 2024, and
the account number valid from September 30, 2024, onward – along with the corresponding amounts
contributed to each - on the 2024 Illinois 1040 Tax Form, Schedule M (see below for example)
Please note: Reportng this informaton incorrectly could result in a delay in processing your 2024 Illinois state
tax return.
