Withdrew from Canada RRIF - reporting NR4 (code 26) on US taxes

I am a dual US - Cdn citizen living in the US who is retired. I withdrew from a RRIF for the first time in 2023 and this was my sole income.  I received a lump sum of $135,000 CDN with 25% withholding of $33,750 CDN.  NR4 has code 26.   Do I create a 1099R?  Will my gross and taxable amount be the same, converted in US $ or is my taxable amount less withholding taxes?  I was anticipating a refund, but my calculations  show I owe close to $7K.  What am I doing wrong?  Married filing jointly.
