Yes, that income should be accounted for in your 2017 Tax Year Business Income. In light of this I would suggest that you contact the issuer of the 1099-MISC and request that they correct the amount of the 1099-MISC and issue you a new document. This is recommended because the IRS does cross-reference the income that you have reported with the income that has been reported on your behalf through instruments such as 1099-MISC.
If you cannot receive a correct document from the issuer you must prepare your return with the correct amount and mail your return with a statement citing the discrepancy. You cannot E-File your return if you choose this path.
