The only look at total income reported on Sch C vs 1099s reported to them by the payers.   As long as the income reported on Sch C meets or exceeds the income reported on the 1099s that IRS has on record, theres no issues.

Ive never once, in over 25 years, input the actual 1099 MISC that clients receive. If they bring me a stack of them, and tell me thats the only income they received, I add them up and stick the total on Line 1 of the Sch C.

I also have never entered the actual 1098 for mortgage interest for Sch A or the 8829, I just input the figures.
