I am preparing a 2019 Form 1040. My client has state backup withholding which appears on Form 592-B. which I entered in screen 55.012. The diagnostic says that the client needs to provide the FTB with their TIN prior to filing the tax return in order to receive credit for the backup withholding.  How do I do that?  I read that Form 592-B is no longer provided to the FTB by the withholding agent.
