Can I put in vehicle registration fee from last year if I forgot to claim it?

Something from 2017?  No, you cannot toss in stuff you forgot to enter on your 2017 return to your 2018 return.  It probably would not be significant enough to make a big difference, but you could amend your 2017 return to include it for 2017.

'Registration Fees' aren't deductible anyhow for personal use vehicles; Only Taxes based on vehicle value are.
