What actually are you trying to perform? Do you compare two proportions?
Chi-square tests that are used in many cases like yours are already right tailed and so are the computer output. So you do not need to take any action.
Hi, if you remember, the density probability functions have a negative side and a positive side, like images in a mirror; and 2-tailed tests uses both sides. But, the Chi test is squared, thus it just has one side including both tails. Best regards.
