I agree with @SweetieJean and although I too suggest you wait you would use form 1040 to file taxes.
Traditionally, unemployment benefits are taxed 10% at the federal level, as well as in some states. You can get ahead of your potential tax bill by opting to have 10% of benefits withheld from your unemployment checks. That said, it's voluntary and often overlooked when people file for unemployment benefits.
