Review
I was getting notices and penalties from the IRS and didn't understand why.
Tatiana investigated and discovered that the issue was that the IRS had misapplied my payment for a prior year, and she called the IRS with me and got everything corrected on my behalf, and got them to remove the penalties.
Tatiana is a real expert, she handled everything quickly and professionally and made the process easy and significantly less intimidating than I thought!
