It is unfortunate that another tax expert decided to answer this question and gave you the wrong information at that. Most of us
do not interfere once an expert has started with a customer, especially when someone as experienced as Wendy is handling the question.
As a tax pro and Enrolled Agent for 25 years, I can tell you that Wendy gave you the correct information, and her answers can absolutely be trusted to be correct.
Please do not hit the green "accept" button for this answer. My only reason for "answering" your question was to be the 4th expert that agrees with the answer that you received from Wendy, and to let you know that having multiple answers from tax experts is NOT normally how this site works, and it was unfortunate that it happened with your question.
Hopefully, this will help set your mind at ease regarding your payment to Wendy, since she gave you the correct information. In the future, if you have tax questions, you may specifically ask for Wendy by name to answer your question, and that will assure that you do not receive differing opinions from other tax experts.
