It's true that TFR numbers provided besides census years are not from directly Chinese bureau of statistics, but calculated by demographers including Chinese ones. However we have relatively fresh data from 2020 directly from Chinese government (census 2020). It was 12 millions births and TFR was provided as 1.3
"China recorded 12 million births in 2020, marking a drop for the fourth consecutive year, while some Chinese demographers warned that China’s number of newborns is likely to drop to below 10 million in a few years, and if no forceful intervention policy is introduced, China’s fertility rate may become the lowest in the world.
The number of newborns in China in 2020 was down from 14.65 million in 2019, and China’s total fertility rate of women of childbearing age was 1.3, a relatively low level, according to the results of the seventh national population census released by the National Bureau of Statistics on Tuesday. "
Now in recent years births have fallen to 9 and 9.5 million. It should be pretty close to the numbers provided by demographers which put China TFR at about 1.1
