Can I file taxes if I get disability :)

Yes if they do a stimulus rebate you will receive that.

Payments you received from a disability insurance policy that you paid the premiums for are not earned income. It does not matter whether you have reached minimum retirement age. If this policy is through your employer, the amount may be shown in box 12 of your Form W-2 with code "J." Then it will be reported as income.

If you retired on disability, benefits you receive under your employer's disability retirement plan are considered earned income until you reach minimum retirement age. Minimum retirement age generally is the earliest age at which you could have received a pension or annuity if you were not disabled.
You must report your taxable disability payments on line 7 of either Form 1040 or Form 1040A until you reach minimum retirement age.

Beginning on the day after you reach minimum retirement age, payments you receive are taxable as a pension and are not considered earned income. Report taxable pension payments on Form 1040, lines 16a and 16b (or Form 1040A, lines 12a and 12b).
