Need to file amended k-1 for business partners

I filled out the partnership profit and loss statement wrong and didn't put it for 50% for the profit and 50% for the loss. I just realized my mistake when filing my personal taxes. Now I need to refile/file an amended business/partnership tax. I cannot find/figure out how to do that, where on/in the TurboTax for business can I refile/resend the amended paperwork?!
