How can I get my tax paper from 2010. H&R block never gave me my papers

If at an office, go get them.
If the office is closed, call the headquarters.
If you filed online, you print them out yourself.

You can get a free transcript of your tax filing from the IRS, which would give you all details of your filing. See:
