Turbotax calculated my IRS underpayment is 42$ . Does turbotax file form2210 on my behalf? How do i pay irs 42$?

- Do i need to pay irs 42$ separately. If so what's the process for this.
- Is 42$ already added to the tax i need to pay irs. So i don't have to pay 42$ to irs separately.
- Will irs send me a separate letter with underpayment penalty and then i pay irs - meaning the turbotax calculation of 42$ is just an estimation.
