I retired in October of 2024. At that time I rolled over my retirement account which included company stock. Most of this rolled over to an IRA. The stock was treated differently and I chose to pay tax on the cost as determined by the issuing company. This added a large sum on untaxed income from a 1099-R which then looks like I was not paying tax on it but it was from a retirement account. This was a one time event and has caused an underpayment penalty that I could not avoid. Is this correct?
