This is not easy. You need to find your Institution Number which is not really part of your account number.
example 3z5-xxxxxx Institution is 3z1 really.
Go to the site to find your Institution number.

Put in the first three characters of you account number into lookup.
ie 3z5 or something else.
Now you have the real Institution number.
This can now be used by the import tool in Turbo tax.
