Can someone please help me! I am trying to remove a dependent from my tax return so that he can receive a stimulus check. I am so confused and always use Turbo tax because it is easy! I need help! He is my boyfriend, and he does not work, but he lives with me so he said it would be OK to add him as a dependent and claim head of household. But, I think it is better that he receive a stimulus check. Can someone please tell me SPECIFICALLY where on my return I can make this change? Is it for State or Federal? I only get lost when I go back in to change any information. Uggh!! I am so lost!! Thank you in advance!!
