adding on gorkhey bro, If you have 2 or more w2s with same employer, the federal is one amount from one of the w2 (if you enter from all w2s, you will end up high tax bracket and looks like you were not paying fed tax for other w2s). This will be tricky, so go to agent in that case , if you are not aware of this. Otherwise, you can try turbo tax which lets you file multiple state tax with 1 federal. Dont know if other e filing supports this.
