Your original post was very confusing. I am not surprised Mary responded initially the way she did.

I have no idea what you meant by you "noted" this and that. I also don't understand what you meant by the IRS not allowing a 1099 form to be printed. How could the IRS stop you from printing a 1099 form? Why would you need to print a 1099 form anyway? If the IRS asks for your W2s and 1099s, just submit all the W2s and 1099s you received.

This, too, was confusing. By "do I need to file a form," did you mean file a 1099? 1040? Schedule C?
Personally, I use a 1040 form to file my individual income tax return, and include a Schedule C. If I got a 1099 (be it from a bank for interest earned or from an MSC for shopper fees), I list the information, including the issuer's tax ID number. For mystery shopping income not accounted for on 1099s, I report that as a combined sum on my Schedule C for mystery shopping.
Finally, as others stated, copping an attitude is usually not productive when asking for help. This is especially true for someone who has a questionable history, such as posting under multiple usernames. Communicate nicely and clearly, and you are likely to find responses in kind. Some of us are not as nice and kind as Mary, even when we try to be.
