How do I get the credit for retention bonus, received in year 2016, but paid in full amount in the year 2017. My employer does not provide me amended W2 for year 2016.

I have received say $10000 of retention bonus in the year 2016. I have paid say $1500 of federal taxes and $500 of CA state tax on this amount. So net in hand I have received $8000 but I had to repay $10000 in 2017. How do I claim the $2000 of tax that I have paid when filing taxes for year 2017 on online turbo tax filing? My previous employer does not provide me with amended W2 for the year 2016.

Thank for you the link. It helps. Can you please let me know how do I enter below information in online version of Turbo tax?

" If you reported it as wages, unemployment compensation, or other nonbusiness income, deduct it as a miscellaneous itemized deduction on Schedule A (Form 1040), "

I do not see such page in miscellaneous forms?

Also, if I had to take credit where do I enter this information in turbo tax ?
