My tax person didn’t report $8 dividend ($2 tax) in my taxes. What will be the consequences?

Hello!

I received dividends worth $8 and taxes on that was $2. When the person who does my taxes tried to put it in the software (Guessing Turbo tax), it said it's too small to report and it won't take it.

My taxes has been filed. What can I do now?

Thanks!
