Form 16 mismatch

I had deposited some cash in PPF account during FY 17-18 and declared the same as investment under 80(c) with my employer. However due to bank's mistake that amount was not deposited in my account. Although I have receipt with me. Now, they told me that it was deposited in account but in current FY. Now my declaration and actual investment doesn't match.
Should I file income tax return by claiming that amount in FY 17-18 or should I pay more tax to avoid any future problems?
Please help.
