Theoretically, if a company paid you $600 or more during the calendar year in fees, they are required to send you a 1099-MISC. The $600 should include fees and bonuses paid to you but NOT REIMBURSEMENTS or other expenses such as the Paypal fees they pay Paypal to transmit funds to you, the shipping costs they pay to send you materials or that they pay directly or indirectly through reimbursing you.
This being said, a company will not prepare or send you a 1099-MISC for amounts under $600. Don't bother asking for one.
You are responsible for paying taxes on EVERY dollar earned, so whether you get a 1099 or not, you may have liability for income and social security taxes. Hopefully you have kept full records of all income and business expenses such that your tax liability, which is calculated on the net profit of your business, can be clearly demonstrated even in the absence of 1099s or the presence of inaccurate 1099s.
Getting 1099s corrected is an exercise in futility unless they are orders of magnitude off (like you earned $700 and the 1099 is for $70,000). You do not submit them as an attachment to your tax return and even under the best of circumstances they are unlikely to match your own spectacular record keeping, so do your return based on your records.
