Correct, you do not want to enter any income twice as it would create a 'double tax' situation. Because those 1099s get sent to the IRS, it is very important that you keep good records of your income. You are one of the taxpayers that receive 2 forms for the same income. The IRS does not expect you to pay double tax but they also do not know that the income is the same, so they may ask. As long as you have your numbers straight, and it seems you do, you won't have a problem.
