I concur with Walesmaven.
Frequently the answer you get from any help line is just an affirmation of what you ask. So if you asked "Should the MSP send me a corrected 1099 because it is wrong in that includes both the fee and the reimbursement for expenses as income?", they will of course say "Yes". If you ask "Should I claim every penny I'm paid and deduct out the reimbursements?", they will probably say "Yes". When you go deeper into 'explanations' and 'what ifs' any help line in the world will start to waffle.
When I have had very specific questions for which I wanted a very specific answer IN WRITING, I have used the IRS email help desk and stated the question in such a way that I would be surprised not to get the answer I wanted. I then have printed off the email to include in my file with my tax return. There were approximately 6 such questions I asked and had answered just with filing the final return for my Mom and for her Estate after she passed. They were questions that were not clear from the instructions and posing the question for a confirming answer took care in crafting. In one case I did not get the answer I wanted so I waited a week and emailed again the identical question. The second time I got the answer I wanted.
Tax code is not exact when it comes to nuances. That is why HRB may find you 'deductions' for last year that JH did not find. Their interpretation of tax code is likely to be different in the nuances and the Tax Court rulings. Was either one 'wrong'? No.
