My brokerage paid me $225 if I transfer certain amount of money to my account on their platform. I did and received the bonus. Is it taxable? If so, how can I report it?

This brokerage send me all needed 1099s, but there is no mention of $225 I received from then in exchange for transferring money from other account into theirs.
Is it taxable?
If it is, how can I report it in Turbo Tax?
