My client uses Accrual basis accounting and I use Cash basis. The 1099 they issued is larger than what I deposited (from them) in 2017 -- how would I resolve this?

One of my clients uses Accrual basis accounting, and I use Cash basis accounting. Consequently, they issued me a 1099-MISC with a larger amount than I actually received from them during 2017. 

Since I have to enter all my 1099s (in the income section), how do I exclude the amount that I did not deposit during 2017?  i.e., so it doesn't conflict with my declared income for 2017.  Thanks


e.g., hypothetically, if they issued me a 1099-misc for $1,000 and I only received and deposited $500 during the 2017 calendar year, how would I handle this in Turbotax.
