Deductions & credits

@ErnieS0  HELP - or anyone else who reads this.  Your response does not answer my question which is: im an employee forced to work from home due to covid.  I rent my apartment- expensive at ~$6000 per month.  I set aside a room as an office for covid work from home.  On my NY State return can i deduct a portion of the rent as a home office expense?  I see no guidance on this anywhere.  Of course I paid rent prior to covid so this is not an incremental expense, but I have set aside and set up one room as an office because of covid.  Please advise.
