Copy rows when value matches a value in another column

Hi there,
Thanks in advance for your help on this! I have a spreadsheet with columns A through U. For any row where column A matches a value in column U, I want to copy columns A through T to another sheet. There will be multiple matches in column A that match a value in column U. I have tried various lookups with arrays and index/match formulas I found on line but no luck. I would greatly appreciate any assistance on this. Thanks!
