RMD Due by Dec 31, 2o25 question please

BOX 7  IRA SIMPLE IS CHECKED  ,  TAXABLE AMOUNT IS 6800.00 .     They figure it out for me for RMD, and I get monthly payments.   So would my RMD by dec 31 2k25 also be 6800?   This is the entire distribution for 2025 and the same listed on my 1099R ?   Thank you.    Also, do you know if I am already getting monthly distributions, is it too late to ask them to withhold tax, or should i just save it and pay at end of year?
