I have skr 1.4 turbo mainboard and tmc 2209 drivers.

I want to use E1 pin instead of E0 pin for connecting extruder stepper. What changes should I do in marlin to make it work ?

edit Marlin/src/pins/lpc1768/pins_BTT_SKR_V1_4.h

#define E0_STEP_PIN                        P2_13
#define E0_DIR_PIN                         P0_11
#define E0_ENABLE_PIN                      P2_12
#ifndef E0_CS_PIN
  #define E0_CS_PIN                        P1_04
#endif

#define E1_STEP_PIN                        P1_15
#define E1_DIR_PIN                         P1_14
#define E1_ENABLE_PIN                      P1_16
#ifndef E1_CS_PIN
  #define E1_CS_PIN                        P1_01
#endif

exchange E0_ With E1_ in this section

Also make sure you have a stepper driver in the E1 socket

That worked thank you. Printer is working normally, but I have "TMC CONNECTION ERROR" on LCD.

I added my conf files.

Updated these also

  #define E0_SERIAL_TX_PIN                 P1_04     ->     #define E0_SERIAL_TX_PIN          P1_01

  #define E1_SERIAL_TX_PIN                 P1_01     ->     #define E1_SERIAL_TX_PIN          P1_04

you have define E0_DRIVER_TYPE TMC2208_STANDALONE

So the micro stepping is set by the jumpers under the stepper driver

Wrong micro stepping results is twice or half expected movement

My guess would be you have all jumpers off so you have 1/8 micro stepping, but you should have 1/16th micro stepping, with two jumpers MS1 and MS2 on
