In 2024, I initially contributed $7000 into my traditional IRA (with $0 balance to start with) thru Robinhood and then Robinhood did a 3% IRA match. This made the total balance in traditional IRA $7210. I converted all $7210 to Roth IRA. I suppose the extra $210 is taxable, yet Line 4b in Form1040 show $0. I then tried to modify Line 8 in Form8606, but Turbotax doesn't let me... Anyone please help me figure out how to make this $210 show up in 4b of Form1040, as this is very annoying. Thanks alot in advance!
