"....... how can i deduct musical equipment, internet, car insurance etc. from it if im not an LLC."
You cannot have it both ways. Either you have been receiving hobby income, or self-employment income. And either type of income was supposed to be put on your tax return. If you had hobby income, you cannot deduct expenses. If you had self-employment income, you can prepare a Schedule C for your expenses.
HOBBY INCOME
