W2

I had a rough year, and had to work multiple jobs. I had about 5 jobs I filed for. Will having that many w2s to file greatly reduce my return? 2 of the jobs I only had for a month or 2. The 3 other ones where 6 months to 5 months

It's not how long you worked at each job but the total income of all for the year.  Basically,  The tax is calculated on your total income.  Then all the withholding is subtracted leaving you with a Refund or Tax Due.
