You enter your employee expenses like you have in past years on Form 2106, but be sure to check the box (or answer Yes if that's how it works) to the question about this is a State-use only 2106 for the Miscellaneous 2% itemized deduction.
The federal return will then ignore that Form 2106 but your entries will flow to the Schedule A Miscellaneous Itemized Deduction Worksheet which is now mostly for state use only, except for the bottom section -- Not Subject to 20% Limitation. TT New York will pick up your deductible expenses from there.
