Divorce court: I need to give other side my tax returns., does he block use a unique font or anything else?

I know IRS will ignore any subpoena from a civil court per tax payer bill of rights. I used h&r block for 10 years now and I hid all the metadata. My worry is they're going to subpoena for stuff I redact and will the bypass the IRS subpoena and go directly to the preparer to subpoena.

The question is whether h&r block uses a specific type of font, that no other tax preparer uses like turbotax or any other software.

I've never seen other tax returns from other preparers.
