Should be able to do it fairly quickly if it's just one word.
There are other solutions but The FinderOuter is one of the quicker / easier ones to use.

For derivation path (BIP39)
m/44'/0'/0'/0/0 for legacy, bitcoin addresses that start from 1
m/49'/0'/0'/0/0 for nested segwit, bitcoin addresses that start from 3
m/84'/0'/0'/0/0 for (native) segwit, bitcoin addresses that start from bc1
One letter typo isn't that complicated to do manually since there are only a few similar words in the BIP39 word list.
Use CTRL+F, then search the typo~ed word's first few characters...
I bet there's more to this than what's stated in the OP like he might have found the correct seed (checksum: ok) but failed to find his balance.
