State tax filing

Thank you for your answer. I reviewed my calculation of underpaid tax before April 15, 2024, it's actually $3. when I actually file my return, would I only pay $3 or $3 and interest on it? 

 

If I need to pay interest, how do I calculate?

Would I pay $3 when filing my state return but pay the interest separately to the State of MI?

 

Thank you,
