Get your taxes done using TurboTax

Firstly, when you made the contribution through your brokerage, you should have been asked what year you wanted the contribution to be for. You can choose the prior year up until 4/15.  You will need to contact them and instruct them that the $7,000 was a 2024 contribution, if that is what you wanted, and they will tell you what steps you need to correct this.

Next, when you report the conversion, you will make sure you are only paying tax on the $2 of earnings.  Here are the steps in TurboTax Online, from How do I enter a backdoor Roth IRA conversion? :
