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?
A brokerage bonus or promotion is typically treated the same way as interest earned in the account. If the account is a regular taxable account, the bonus will be taxable. I expect at the year-end 1099-INT will include this bonus. If it does not you should post it as interest.
You can enter your 1099-INT manually.
Go to Wages & Income
Work on other income
Investments and Savings
Interest on 1099-INT
Add Investments Or select 1099-INT
Relax. We got it. = Continue

Enter your new information.
If the account is a traditional IRA, there won’t be a 1099 and therefore it won’t be taxable in the current year. But because the bonus stays in the IRA and it grows tax-deferred, eventually when you withdraw the money after you retire, the money will be taxable at that time.
