State tax filing

The contributions line is having you add two different accounts. One of them, had a withdrawal greater than the addition. Sons contributed $650 withdrew $1700. Daughter, contributed $1050.

This means: the contribution that counts is only your daughters, $1,050.

For your sons, you had contributions of $650 and withdrawal of $1,700 which included the current year of $650 so it is washed out. So your two entries, will match. $1050 each since they are different accounts.
