I have a business I run doing digital work for clients. One client has issued me a T4A for the amount they paid me. So this goes under T4As. Then I go to do my business to entry the relevant information there and when it comes to putting in the income I cannot get it to show up under income on T4As. So anything I enter here is making it look like I earned double of what I really did. Regardless of what I do it will only give me an option to put income "not on a slip" in. The values under "self-employment commissions from T4A slips don't every update they stay as $0. Not sure what intuit changed this year but it's worked fine for the last 4 years I've been doing this self employed business and haven't had this problem.
Please double check that you've entered your T4A information correctly. Then check if TurboTax isn't putting the T4A amount on a second business form. You can do this by clicking on Tax Home on the left side menu, then click on Self-Employment on the Tax Home page. Then click on Self-Employment again to see a list of all your business forms
If your T4A has accidentally gone to a second form, then you can just fill out the basic info on that form and continue with your expenses etc... on the original form.
