Because it's a change of income, you'll need to file an amended return unless the IRS corrects it for you.
Wait until the original processes. If the IRS does not suggest the correction, file a 1040X Amended return.
It should not result in additional tax, but there are credits that are based on your income, so your tax liability might adjust. If you will owe, be sure to have that paid by April 15th.

Thanks, couple more questions. What about the corrected 1099? Do I delete the original and re-enter the corrected 1099? I've paid almost $2,000 in 2018 taxes and adding the missing 1099 forms will cause be to owe a little more. Are you saying I have to file the amended return before April 15? IRS accepted my return the same day I filed it.
Yes, you delete the original and enter the corrected 1099. You need to pay any additional tax by April 15th, but the 1040X does not necessarily need to be sent by April 15th.
The amended return (1040X) will show you the difference, so if it shows tax due, this will be in addition to what you paid with the original return.
It is best to wait until the original has processed, the IRS may even correct for the 1099, in which case they will notify you by mail and ask if you agree with the re-adjusted tax.
