Does workman’s compensation count as veteran’s income on the VA A&A application?

Yes.  See following from 38 CFR 3.262

(i) Compensation ( civilian ) for injury or death. (1) Compensation paid by the Bureau of Employees' Compensation, Department of Labor (of the United States), or by Social Security Administration, or by Railroad Retirement Board, or pursuant to any workmen's compensation or employer's liability statute, or damages collected because of personal injury or death, less medical, legal, or other expenses incident to the injury or death, or the collection or recovery of such moneys will be considered income as received, except as provided in paragraph (i)(2) of this section. The criteria of paragraph (i)(1) of this section are for application as to all medical expenditures after such award or settlement.

(2) Life insurance; general. In determining dependency, or eligibility for dependency and indemnity compensation, or for section 306 pension the full amount of payments is considered income as received. For section 306 pension, effective October 7, 1966, and for dependency and indemnity compensation, effective January 1, 1967, 10 percent of the payments received will be excluded.
