I would wait till you get the final number from the company issuing the 1099. They should be able to tell you what that number is, and how they arrived at it. Make sure it agrees with your records. If not, make sure they explain the discrepancy to you.
It's important that you report the exact number that they show on the 1099, because the IRS has a program where they match what the business sends in and what you report on your 1040. If there is a difference and you under-report the income, they will calculate a new tax plus charge you penalty and interest for under-reporting income.
These notices usually come out much later in the year, and they are a real pain to deal with. So, if you can be patient, it's to your advantage to wait to get the correct 1099 from the business before submitting your return.
