Workflow: using question response to point to Google sheet tab

We have a survey that uses branches to take respondents to specific blocks of questions based on an initial question.  In other words, answer A sends respondents to block A, answer B sends respondents to block B, etc.  Using a workflow, survey results are exported to a Google sheet.  What I’m attempting to do is use a condition to direct the responses to corresponding tabs in the Google sheet.  So if one respondent answered A & completed the A block questions, their results go to the A tab, while someone who answered B & completed the B block questions has their results go to the B tab, and so forth.  I’m having trouble attaching the tasks and conditions.  Can someone help me some instructions or a link?  Thanks.
